There exists in your physical organism reserve stores of vital energy stored away for your use, particularly in that central ganglion of your vital battery known as the Solar Plexus and generally in the chain of ganglia or storage batteries along and up your spine and elsewhere in other nerve-centres. The solar plexus is also known as the Abdominal Brain and your brain depends and draws upon this vital centre for its energies. You will find after the prolonged concentration and brain-work that this part of your body--at the back of pit of stomach--becomes warm. Now when you engage in physical exercise, for instance, you must have noticed how at first you soon get tired and all done up. But if you wait a little and then start again, you will find how the sense of fatigue has quite passed away and you can run your body under full pressure for a very long time, and the more you exert yourself the greater and more powerful the surging up of your vital energy. With each new exertion you seem to acquire a fresh start. This has puzzled physiologists. You will find a parallel phenomenon in mental work. You may experience a sense of weariness and fatigue in some brain-work which demands close thinking and attention, but if you attack your work a little later after the first effort you will do your work a surprising degree of freshness, vigour, and enthusiasm far surpassing the original attempt. Again everyone can and does put forth universal energy under pressure of some urgent necessity, which will startle even himself. No matter who you are and what your physical condition, there is an enormous amount of power in your body that has never been drawn upon at all and impatiently waiting for up-call. We go on in ordinary dog trot pace, resting, limping, "taking care of our health," and then we think we are doing our best. Do not permit your mind to be self-hypnotised into a false sense of being "exhausted" and "old." Neither of them is a fact except in your thought of yourself. All your powers are lying dormant. All your latent energies are lying unused. Back of your conscious mentality are tremendous energies awaiting the pull of your will. When your brain conceives of being something unusually great, at least so it may appear from your view-point, do not question your strength but go ahead unhesitatingly, fearlessly and steadily. Assert your life-force. Feel that you are young, strong and healthy and fit. Live in mental consciousness of power and never think of weakness. Keep your grip and run right along. Nature is sure to honor your draft. Nature is sure to give you strength, energy and vim, in boundless measure. Just try this my friends, you, who write me of "there being a serious lack of vitality" in your system and hence your inability to grapple with the occult. No such thing. Fact is you lack courage and initiative, pluck and "go" and you are labouring under the hypnotism of weakening thoughts. Just change
